SESOC ESE Presents:

Ductility demands for concrete members and detailing required to accommodate them

In contrast to earlier editions, New Zealand Standards since the mid-2000s have required ductility demands and consequently required detailing to be checked based on local deformations of individual elements rather than on overall displacements of a complete structure.

This presentation will:

·Overview why it is important to consider deformation demands at a member, rather than structure, level,

·Review the reasons detailing is required in order for reinforced concrete elements to sustain large plastic deformations,

·Explain the basis of the method used by the New Zealand Concrete Structures Standard, NZS 3101 for quantifying member ductility demands, and

·Demonstrate the application of this method to determine ductility demands for typical elements.

Nic is a consulting engineer and Principal at Compusoft Engineering, having previously lectured in the Department of Civil & Environmental Engineering at the University of Auckland. He has a broad experience in analysis, design and research related to reinforced concrete, including having had extensive involvement in the assessment of earthquake-damaged structures in Christchurch and Wellington.

Nic is widely involved in the structural engineering community, being a member of the SESOC Management Committee, Vice President of the Concrete New Zealand Learned Society, a member of a number of ongoing research projects including the ReCast Floors collaboration, and a frequent presenter of industry seminars. Nicholas was also technical editor and chair of the committee responsible for producing the revision for Part C5 of the assessment guidelines that was released in late 2018.
